A Viscous Damping Device
Our Linear Damper product line is a viscous damping device that acts in one direction, or in-line with the damper axis.
The device is commonly attached between a vibrating pipe and a rigid support (ground, stiff I-beam, etc.).
Installed in Pairs
Most commonly they are installed in pairs with the dampers arranged to resist the vibration. The application to the pipe is as shown to the left.
The connection to the pipe is done with a U-bolt clamp with additional stiffeners to rigidize the connection to the termination on the rod. Clamps can be lined with gasket material to reduce the risk of wear between the U-bolt and the pipe. The damper is position between the pipe and the tie point with the tube length adjusted during assembly.
Termination plates allow for anchoring to a floor, heavy beam, etc. as available, or can be welded in place.

The goal for the devices is to limit vibration below the common vibration screening criteria of 0.5 in/sec pk after installation.
